beltex··on Stripe bans Trump campaign
“All animals are equal, but some animals are more equal than others.”

— George Orwell, Animal Farm

I understand the moves by Stripe, Twitter, and co. However, I would argue that the long term implications set by this precedent are much worse. When the Snowden story first broke back in 2013, many on HN argued that, hey it's all good, I have nothing to hide, and I trust our President. Three short years later, who took the office? Would you have every imagined that? The same goes for this. Think five minutes into the future if you will.

If the leader of the free world can be banned from all social media and co, who are based in the very same nation, and who are monopolies, then what hope is there for the rest of us?

beltex··on Who still needs the office? U.S. companies start cutting space
The elephant in the room to me is that companies talked a ton about creating spaces that are conducive to great work. The design and architecture of an office matters. Not all have it right, but for those who do, it goes a long way. See Pixar as an example. But all of a sudden everyones acting as if none of that matters, all because we get to skip a commute and sit in our pyjamas?

You truly don't know what you've got till its gone...

beltex··on XNU target config for Raspberry Pi 3 (2016)
About the 2016 tag that was added to the title. While the header does say 2016, I think it's that the file wasn't made open source by Apple till this weekend.

Aside - explicit reference to Raspberry Pi here:

May he rest in peace.

Glioblastoma is particularly awful, even in the realm of cancer. Two books I found quite interesting on neurosurgery and cancer as a whole.

beltex··on Former Tesla Firmware Engineer Discusses the System
While were on the topic:

USENIX talk from VP of software at SpaceX (2016)

https://www.usenix.org/conference/lisa16/conference-program/...

(Speaker was concurrently interim VP of Autopilot at Tesla for a bit as well)

Few interesting bits:

- Speaker’s background is SRE at Google

- Engineering culture: Authority, autonomy, accountability. Blameless postmortems

- High Integrity C++ & MISRA coding standards

- The spacecraft has multiple onboard computers, all running Linux

- Tripe String Architecture, 3 redundant computers, whose results are cross checked with majority voting before being applied in real time, given radiation tolerant over radiation hardened hardware

Indeed. Given the number of down votes, either folks didn't catch that, or it's all the short sellers :)
beltex··on Tesla Q1 2018 Vehicle Production and Deliveries
"Tesla Goes Bankrupt

Palo Alto, California, April 1, 2018 --

Despite intense efforts to raise money, including a last-ditch mass sale of Easter Eggs, we are sad to report that Tesla has gone completely and totally bankrupt. So bankrupt, you can't believe it."

beltex··on Tesla’s Musk Takes Charge of Model 3 Production as Problems Persist
"Can’t believe you’re even writing about this. My job as CEO is to focus on what’s most critical, which is currently Model 3 production. Doug, who I regard as one of the world’s most talented engineering execs, is focused on vehicle engineering."

"About a year ago, I asked Doug to manage both engineering & production. He agreed that Tesla needed eng & prod better aligned, so we don’t design cars that are crazy hard to build. Right now, tho, better to divide & conquer, so I’m back to sleeping at factory. Car biz is hell …"

beltex··on Should I use Xcode 9.0.1 given the bad reviews in the App Store
You can download Xcode (and many versions past) here, directly: https://developer.apple.com/download/more/

Thus, you can have multiple versions installed simply by having Xcode.app in a different directory or renamed. Just remember to set the active Xcode for command line usage via `xcode-select` (can verify via `xcodebuild -version`).

This is precisely for jumping between various GM and beta versions in case of issues and such. Downloading from the Mac App Store does not give you this control.

Finally, Xcode 9.0.1 has worked smoothly for us so far FWIW.

beltex··on RFC: Lanai backend – Google internal processor architecture
"This is internal hardware for us, so there's not a lot we can share, and you can't really grab a version of the hardware. If that's a problem for the community, I completely understand.

Mostly, I wanted to offer to upstream this because it seems likely about the same utility as the AMDGPU backend for folks without an AMDGPU, or the XCore backend, etc. It's small, and we're happy maintaining it and taking on any of the effort around it."

beltex··on Tesla Model X Crossover 'Signature' Series Starts at $132K with 240 Mile Range
"With same options, Model X is $5k more than an S due to greater size & body complexity. Sig Series is fully loaded, hence high price."

beltex··on MARS-500
"Marina Tugusheva, the only woman of the crew, was excluded from the longer missions, to prevent sexual tension from jeopardising the mission."

Thats from the year 2009 folks! Depressing :(

She put it best

"Anyone who's ready to participate in space exploration should treat it as serious work. Quite consciously we must treat others as not men and women but as colleagues" [1]

beltex··on MIT discovers batteries with indefinite lifetimes using solid-state-electrolytes
Exciting!

”My top advice really for anyone who says they got some breakthrough battery technologies is please send us a sample cell. Don’t send us PowerPoint, ok, just send us one cell that works with all appropriate caveats, that would be great. That sorts out the nonsense and the claims that aren’t actually true. Talk is super cheap. The battery industry has to have more BS in it than any industry I’ve ever encountered, it’s insane.”

Note this is from 2009 (before Go was on GitHub, and thus the gopherbot comment imports).

Apple ran into a similar issue with Swift.

beltex··on SpaceX CRS-7 Failure Investigation Teleconference Thread
“Now before every flight I always send out an email company-wide saying, ‘If anyone can think of any possible reason to hold off on launching, they should call me immediately on my cell phone or send me an email, whether their manager agrees with it or not.’ But thats sort of something I’ve always sent before every flight, but the 20th time I send that email it just seems like… you know, ’There’s Elon being paranoid again’, so maybe it doesn’t resonate with the same force. But I think now everyone at the company appreciates just how difficult it is to get rockets to orbit successfully and I think we’ll be stronger for it.”

beltex··on Tesla CTO: Batteries and Solar Will Lead to Cheap Electricity Within 10 Years
Elon was asked about a replacement CEO in late 2014, he stated that there currently was no one in mind, and that the plan was to stay on as CEO till volume production of Model 3 and the Gigafactory, and then evaluate [1]. Of course, he may not have been at liberty to say the person in mind.

beltex··on OS X BSD System Calls Reference
"The kernel of NeXTSTEP is based upon the Mach kernel, which was originally developed at Carnegie Mellon University, with additional kernel layers and low-level user space code derived from select parts of BSD." [1]

NeXTSTEP became the basis for OS X. It meets the Single UNIX Specification [2].

beltex··on Tesla Is Working on Robotic Snakes That Emerge from the Wall to Charge Your Car
This was originally mentioned by Elon back in October at the launch of the Dual Motor Model S and Autopilot event. It was in reference to the cars new ability to park itself.

“Something I’d like to do, which I think many of our engineers will be hearing this in real-time, is have the charge connector plug itself in. Like an articulating, like sort of a snake, like Metal Gear Solid or something.”
